Anecdote

Definition:
a short summary of a funny or humorous event.


Example:
If someone were talking about the misuse of law enforcement, for example, they might tell a story about how a man in charge of road cleanup was ticketed for littering when a scrap of paper he had already picked up off the road blew out the back of his truck.
